Weir and locks erected by Sir Thomas Stanhope, in connection with his mills at Shelford. Shown on a map of c 1592 (documentation for legal disputes over the weir, which was pulled down in April 1593, and repaired). (1)
The weir (as shown on map) appears to consist of stakes, probably of willow, driven into the river bed. The locks worked like a portcullis - 2 vertical wooden pillars supported a horizontal beam and 2 capstans, while sluice gates, braced by cross members, hung below. Apparently built in 1576, and therefore the second oldest recorded pound lock in Britain. (2)
